8 Microphone Input Interface The input uses an X9-6Z signal input receptacle. The receptacle pins are arranged as shown below. The pins have the following functions: Pin 1 Power supply Pin 2 Null Pin 3 Signal input Pin 4 Null Pin 5 Signal ground Pin 6 Null On the input receptacle, pin 1 is the power supply pin that the analyzer uses to transmit power to the sensor (36 V, 2 ma max.). Inside this power supply, a 2 kω current limiting resistor is connected in series. The signal input pin receives the input electrical signal, in which a DC isolated capacitor is connected (Maximum input voltage: 10 V (RMS), input impedance: 150 kω, input capacitor: 100 pf). Two optional extension cables are available to place the microphone away from the unit: up to 5m (15 ft) Model MC15 or up to 20m (60 ft) Model MC60. Output interface The bottom of the S665 has three signal output receptacles. The left one is AC output receptacle. This receptacle is a stereo output. When it is matched with the plug, the plug s pins are defined as shown: Signal Fig. 1 Ground Fig. 2 Output Receptacle 3.5mm Output Plug The AC output is proportional to the input signal. The proportion between the output and the input is related to the analyzer s range controller. When the range controller is in -10 db shift (namely the maximum measuring range shift), the AC output is times of the input signal. The AC output signal s output impedance Page 4

9 is 1 kω. It is recommended that the connected load resistor be higher than 100 kω and the connected load capacitor be lower than 200 pf.
